The link works fine for me. It's the last post on this page if that helps.

Or the last post in this thread?

Maybe just restarting Firefox will be enough?

And if you really want to see the post, it's the To swappiness or not to swappiness, that is the question... thread in the Chat about Linux section just below this section.

Are the posted figures taken from an average of several tests or a single run with each configuration?

A single run. It's a lot to do at that.

Thanks for answering and yes it is a rather time consuming task. The single results explain at least some of the wide margin between btrfs results (and apparent lack of for ext4 if I read it correctly) but I'm not expecting you to run them again more times for an average to cancel out any variances from background tasks, file cache etc.

I'm sticking with ext4 for the foreseeable future anyway. I have used btrfs with openSUSE and Fedora before now and wasn't overly comfortable with it. It's a bit too complex for a single drive setup in a consumer machine. Snapshot speed and compression are the only marginally enticing things but I'm not in any danger of running short of storage and rsync is quick enough. Ext4 also doesn't need scrub or balance running to keep it performing optimally (something you should do VERY sparingly anyway on SSD drives).

I like Btrfs a lot. Right now, I'm using it for root and Ext4 for home. I've used it for years in many configurations.

Anyone interested in the Btrfs edit to /etc/fstab it looks like this for root

Code: Select all

defaults,subvol=@,noatime
and for /home like this

Code: Select all

defaults,subvol=@home,noatime
